Thripobius javae

Thripobius javae (Girault)

(Formerly known as Thripobius semiluteus Bouček).

Systematic position: Insecta, Holometabola, Hymenoptera, Apocryta, Chalcidoidea, Eulophidae.

Morphology: Adults are 0.5-0.8 in length, head and thorax shiny black, abdomen yellow with 2 posterior dark spots, legs and antennae yellow.

Life history: A uniparental, solitary endoparasitoid of several Thripidae, especially Heliothrips haemorrhoidalis. It attacks first or early second stage host larvae. Fecundity comes to 60-100 eggs/female, the life cycle is 3-4 weeks (when honey is available), and adults live for 4-5 days. The optimal temperature is 25°C, whereas much mortality occurs at 30°C.

Economic importance: An important natural enemy of several pestiferous Thripidae, like H. haemorrhoidalis and Hercinothrips femoralis, and may cause about 50-60% host mortality. Due to the fact that T. javae develops faster than H. haemorrhoidalis, it may reduce the pest’s population levels. Its pupae can be stored at 10°C for up to 14 days, with only a moderate (33%) reduction in fitness. Thripobius javae was successfully introduced into Italy and New Zealand.
